Re: CloudStack DNS names to PowerDNS export


Hello, Community.

Several days ago I wrote about small service that automatically creates
service domain names for CloudStack VMs created. Just would like to publish
small updates which may be interesting to you.

1. The code was updated to use mysql.connector instead for MySqlDb (thanks
to Wido Den Hollander)

2. I have implemented domains support defined for CloudStack accounts,
before - only domain-level DNS suffixes were supported, so, now every
account can have separate DNS zone if it's defined.

3. I have implemented group-based domain names. They may be very beneficial
to those, who create fault-tolerant scalable services with CDNs like
CloudFlare. Now, all VMs created in a single CloudStack group are placed
into a single "group-based" FQDN, so DNS can return multiple A/AAAA records
for a single name. Using this FQDN as CNAME in CloudFlare enables automatic
failover, scalability support without efforts. Just create new VM in the
same group e.g. www and it just works. Want scale down, remove excessive
VMs.
